NI constituencies and local authorities were filled with UK-wide mean age profiles, ignoring that NI has a younger population. Now uses NI-specific age distribution from ONS subnational projections. - Update fill_missing_age_demographics.py (both constituency and LA) to use country-specific means instead of UK-wide mean - Regenerate age.csv files with NI-specific profiles - Add 6 tests verifying NI profiles differ from UK mean, Scotland has distinct profiles, and NI young share exceeds UK average Closes #64 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Document data sources in both README.md files: House of Commons Library, Nomis, ONS subnational projections, NISRA - Expand from 6 to 13 tests: add expected counts, age-sum-to-all, no negatives, NI younger share (LA level), country presence checks Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
